The amplitude of your signal goes from -4 to 0, so the ‘zero-crossings’ in your signal are correctly detected at the highest value of each cycle. If you want the indices where the signal crosses the -2 value, the ‘zci’ call should be: Theme. Copy. zx = zci (y + 2); % Approximate Zero-Crossing Indices.
